Double Chronograph

A split-seconds hand or rattrapante is an additional seconds hand on mechanical chronographs. The split-seconds hand, which runs underneath the stopwatch hand, can be stopped independently using a push-button at “10 o’clock”, while the stopwatch hand continues to run. This allows the user to record two separate times, precisely to the second, within any given minute. If the third push-button is pushed again, the split-seconds hand instantaneously catches up and is synchronized with the stopwatch hand. It is then possible to record a new intermediate time.
